Model # 02032C Wind Gust Spikes

Hello. I have the Model # 02032C 5 in 1 and I get wind spikes almost daily. I'm in Texas and this time of the year we don't have many wind days, it's just ho. But I will get alerts for wind gusts of 50mph and more. It happens mostly at night but I've had a few during the daytime as well. Any reasons why?
